Theactuator 28 is rigid with 95 lo called book. the actuator 11, and diametricallyopposed As thus illustrated, the book leaves 1 are thereto, and normally this actuator l28 each double and formed with a loop at their passes the outer end of the arm 19, as shown outer edges, while the other edge portions' in Fig. 3 of the drawings. However, when are clamped between the angle irons 2 on the the cam portion 23 strikes the cam portion 1m) support 3, and are held in place by nails or 24, the arm 19 is then forced into the posipins 4 inserted in the manner shown. The tion shown in Fig. 4C of the drawingsand wires 5 are inserted in the loops of the leaves, this brings the outer end of the arm 19 into as shown, at their outer ends, and their inner thepath of the actuator 28, as shown in ends are rigid with the cams 6 mounted on Fig. 4, with the result that the arm 19 and 105 the shaft or wire or axis member 7 in the the rack 17 are rotated a distance aboutthe manner shown. Back of the shaft 7 a shaft axis of the shaft 8, thus swinging the mem- 8 is suitably mounted on the body `tran'ie of bei' 29 from the lefthand side over to the the machine and upon this shaft is a cylinder righthand side, and thus carrying all Aoi 9 which carries a set of' radial pinsor lingers the wires 5 over to the righthand side of the 110 5.5 10 to be engaged by the actuator 11, and machine, thereby restoring all oi' the leaves which carries the staggered or irregularly ar`` to the righthand side of the book.` This,

Y be applied to the rackl7 to restore the member 19 `to the position shown in Fig. 3 of `the drawings, as soon as the actuator 28 slips olf from t-he end of the arm 19, thus automatically restoring the mechanism to the condition shown in Fig. 3 of the drawings. When the leaves are thus all turned to the right, the wires `5 and the leaves then rest against the stationary member 32, and at such time the member 29 rests normally against the stationary member 83 of the frame or body of the machine.

The power for operating the shaft 13 may be of any suitable or desired character. For example, the wheel or pulley 34 shown in Fig. 1 can be rotated by any suitable power to rot-ate said shaft. This shaft, when continuously rota-ted, causes the machine to automatically turn the leaves successively to the left, looking atthe macihne and Ybook in the direction of Fig. 2 of the drawings, and as soon as the leaves have all been turned over to the left-hand side, they are then automatically and simultaneously returned to the righthand side of the book, in the manner shown. Thus an automatic book leaf turning machine is provided which is operative to turn the leaves in a natural manner, beginning atthe front of the book and turning the leaves successively, and until they have all been turned over to the left. The machine is then operative to `instantly and simultaneously return all of the leaves to the right, or to the back of the book, so to speak, and when this has been done the ma- 'chine is then operative to automatically again `turn the leaves successively in the i desired manner. Therefore, the automatic turning of the leaves, successively, from the front `of the book toward the ack, is an operation that alternates with the automatic turning of the leaves simultaneously to the right to restore them to the position in which the leaves are superposed one upon another, just as `they would be in an ordinary book when the reader starts to read the book. This series of successive leaf turning operations is completed before. the leaves are turned backward, of course, so that the machine has as many leaf turning operations as there are leaves to be turned, in one direction, and in this way the complete leaf turning operations alternate with the leaf` restoring operations., Each complete leaf turning operation to the left is made up of as many successive operations as there are leaves, but each leaf restoring operation consists of only one operation for all of the leafv turning wires in unison, to the right, instead of turning the leaves back one by one or successively.

The leaves of the book, it will be seen, are flexible, desirably so, inasmuch as they are held tightly between the angle irons 2 at the back of the book. The turning of the leaves exposes to view both surfaces or pages of eachleaf and the speed or rapidity with which the leaves are turned will depend, of course, upon the speed of rotation of the shaft 16, for the complete rotation of this shaft is necessary for the turning of each leaf. If this shaft 16 is turned over slowly, as by the worm gear mechanisms 14 and 15, it follows that the leaves will be turned over slowly, but this can be timed in any suitable or desired manner, by proportioning the gearing and other parts, fas will be readily understood.

Preferably, the book occupies an inclined position', as shown in the drawings, and the axes of thecylinder 9 and the shaft 7 are inclined accordingly, whereby the machine may be placed in a store window with the book in an inclined position to be easily viewed by people outside.

But while the invention is especially adapted for advertising and display purposes, it will be readily understood that the machine can be used for turning the leaves of a book under other circumstances and for any suitable or desired purpose without departing from the spirit of the invention, and the invention is not limited to the exact construction shown and described, or to any particular use thereof.

It will be seen that the elelnent 29 restores all of the members 5to normal position, simultaneously, and that this element 29 is then restored to its normal position before again starting the turning of the leaves singly, thereby to permit said members and the instrumentalities for actuating them to again cause the successive turning of the -leaves to` display the pages thereof.

lVithout disclaiming anything, and without prejudice to any novelty disclosed, what I claim as my invention is:

1. In a book leaf turning machine, the combination of members for engaging and turning the leaves, instrumentalities having means for converting continuous rotary n1o tion into intermittent rotary motion for causing said members to automatically turn the leaves forward one by one or successively in one direction, an element for causing actuation of all of said members in unison, in the other direction, after all of the leaves have been turned in said one direction, and devices automatically to cause the actuation lll) of said element at the proper time, to turn all of the leaves back, together with means operative automatically to cause the restorA tion of said` element and said devices to normal condition, after the said restoration of all the leaves, and before again starting the turning of the leaves singly, thereby to permit said members and said instrumentalities to again cause the successive turning of the leaves to display the pages thereof.

2. A structure as specilied inclaim 1, said members comprising Wires bent to engage the outer portions oi' the leaves, and said instrumentalities comprising cams rigid With said wires, rotatable about a common axis, and including also lingers disposed in position to engage said cams successively, said ngers being rotatable about an axis parallel with said axis of the cams.

3. A structure as specified in claim 1, the leaves of the book being held together at the back of the book, the leaves being flexible to permit the turning thereof, and the outer portions of the leaves being double and forming loops in which said members are inserted.

et. A structure as specified in claim 1, said leaves having loop portions at their outer edges, and said members being inserted in these loop portions, and the leaves being iiexible.

5. A structure as specied in claim 1, said devices for causing restoration of said ele ment, comprising a rotary actuator, an arm normally out of the path of said actuator, cam means for automatically moving said arm into the path of said actuator and `gearing operated by said arm to actuate said element.

6. A structure as specified in claim 1, said instrumentalities comprising cams rigid With said members, rotatable about a common axis, and including also iingers ar 'anged radially and spirally about an axis parallel With the axis of said cams, each linger being in line with a different cam.

7. In a book leaf turning machine, in cooperative combination, swinging members for engaging the leaves to turn them singly in one direction, and instrumentalities for causing' the actuation of said members, the leaves ot' the book being held together at the back of the book, the leaves being flexible to permit the turning thereof, and the outer portions of the leaves being double and forming loops in which said members are inserted.

8, In a book leaf turning machine, in co operative combination, swinging members for engaging the leaves to turn them singly in one direction, and instrumentalities for causing the actuation of said members, said leaves having loop portions at their outer edges, and said members being inserted in these loop portions, and the leavesbeing liexible.

9. In a book leaf turning machine, in combination, a plurality of swinging members tor engaging the leaves oi' the book, to turn them singly in vone direction, mounted to swing about a common axis, a rotary elesaid mechanism comprising another set of adial lingers on said element, disposed in one and the same plane, and comprising continuous rotary motionmeans for successively engaging these last mentioned lingers to rotate said element and irst mentioned 1ingers intermittently.

11. A structure as specied in claim 9, in combination with instrumentalities controlled automatically by portions of said mechanism to simultaneously turn all of the leaves back to normal position, after they have all been turned singly forward.

12. In a book leaf turning machine, the combination of members ttor engaging the leaves, instrumentalities for causing said members to turn the leaves one by one or successively in one direction, an elem-ent for causing actuation of all of said members in unison, in the other direction, after all of the leaves have been turned in said one direction, and means automatically to cause the actuation of said element at the` proper time, together with devices to cause the restoration of said element and said means to normal condition, after the said restoration of all the leaves, thereby to permit said members and said instrumentalities to again cause the successive turning ot the leaves to display the pages thereof,` said members comprising Wires bent to engage the outer portions ot' the leaves, and said instrumentalities comprising cams rigid With said wires, rotatable about a common axis, and including also fingers disposed in position to engage said cams successively, said fingers being rotatable about an axis parallel With said axis of the cams.
